A trapezoid is a quadrilateral with one set of __________ sides.

70% Answer Correctly

	parallel
	equal length
	equal angle
	right angle

Solution

A trapezoid is a quadrilateral with one set of parallel sides.

Simplify (y - 2)(y - 1)

63% Answer Correctly

	y² - y - 2
	y² - 3y + 2
	y² + 3y + 2
	y² + y - 2

Solution

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses:

(y - 2)(y - 1)
(y x y) + (y x -1) + (-2 x y) + (-2 x -1)
y² - y - 2y + 2
y² - 3y + 2

If BD = 23 and AD = 28, AB = ?

75% Answer Correctly

	6
	5
	1
	2

Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 28 - 23
AB = 5

Which of the following is not a part of PEMDAS, the acronym for math order of operations?

88% Answer Correctly

	addition
	division
	exponents
	pairs

Solution

When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)

A cylinder with a radius (r) and a height (h) has a surface area of:

53% Answer Correctly

	π r²h
	π r²h²
	4π r²
	2(π r²) + 2π rh

Solution

A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r²h and the surface area is 2(π r²) + 2π rh.
